there are many ideas and theories about art appreciation,
and what one needs to know in order to appreciate a work of art.
it appears to be true that art can be appreciated without knowing who, what, where, when, why - or how.
it is possible to only have the raw sensory experience of a thing - and then to extrapolate (or not extrapolate) any further meaning or purpose, and to just appreciate a thing for its semblance and beauty.
but what happens when you do find out the who, what, where, when, why - and how.
